Energy Conservation

  1. 1. <ul><li>981 Sciences for Designers </li></ul><ul><li>Week 8-II </li></ul><ul><li>The Conservation of Energy </li></ul><ul><li>Applications </li></ul><ul><li>Green or sustainable energy </li></ul>
  2. 2. The science behind the deadly roller coaster ride in the movie Final Destination 3
  3. 3. How to design a thrilling roller coaster ride? - This will be a project in design fundamentals in the next semester.
  4. 4. Basic elements of a modern roller coaster
  5. 5. The track for the roller coaster can be an artwork .
  6. 6. <ul><li>The principle of a roller coaster : </li></ul><ul><li>lifting the train to a very high place . </li></ul><ul><li>Letting the train fall freely due to gravity . </li></ul><ul><li>The geometry of the track is designed to meet desired fear factor . </li></ul>
  7. 7. What is the fear factor ?
  8. 8. People feel afraid, or excited, when their speed or direction of motion is changing; that is, when they are accelerated . acceleration in speeding up S S 0-100km/h 12s 3.8s a a
  9. 9. acceleration in changing direction a a
  10. 10. What causes the sense of fear to people who are accelerating? The acceleration of an object cannot be enabled without a push or pull from another object. S S Newton’s 2nd law: F
  11. 11. 50km/h S S S S rest, 0km/h a F
  12. 12. An authentic example of in measuring force via acceleration interaction design MS X-Box 360 control for the next generation
  13. 13. Therefore, as long as we know the acceleration of a person experienced at each points along the track, we can orchestra the variation of fear factor. But how? We need one more knowledge …
  14. 14. v=0 v=0 v=0 不變
  15. 15. a 不變
  16. 16. Summary To design a roller coaster ride, <ul><li>lifting the train to a very high place . </li></ul><ul><li>Letting the train fall freely due to gravity . </li></ul><ul><li>The geometry of the track is designed to meet desired fear factor . </li></ul>Determine U+K Let U  K Change height & curvature (R) to acquire desired a
  17. 17. 能量轉換 (between U & K ) Are they other forms of energies? 直指 : 能量守恆定律
  18. 18. Why, in the tragedy in the movie, did the train stop at the top of the loop? v=0 Because some of K+U is taken away by friction , in to heat . Heat (熱) , K( 動能 ) and U (位能) are three types of energies.
